feat: Implement complete style-aware editor interface (Phase 2)
- Add StyleAwareEditor class with intelligent editing strategy detection - Implement three editing modes: simple text, rich content, multi-property forms - Create dynamic formatting toolbar with buttons for detected styles - Add multi-property editing forms for complex elements (links, images, buttons) - Integrate contentEditable with style application/removal functionality - Replace markdown-based editor.js with style-aware architecture - Add comprehensive CSS styling for modern, responsive editor interface - Support fallback editing for error cases with graceful degradation - Enable real-time style application to selected text in rich editor - Preserve all element attributes and structure during editing workflow Complete implementation of CLASSES.md style preservation specification. Phase 2 foundation ready for final testing and refinement.
